Thread: Check for larger num problem

the problem is as follows:

Create a main class file. (1) Inside create a method max() that has two floating point
parameters x and y and returns the larger of x and y; (2) In the main method, input two
numbers from the keyboard, and then use the max() method you created to compute the
larger value and output it.

this is what I have so far but am confused on how to get my max method to return the larger sum

 
 
import java.util.Scanner;
public class LargerNum {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("Enter two values: ");
		double FirstNum = input.nextDouble();
		double SecondNum = input.nextDouble();
		double Final = MaxMethod(FirstNum, SecondNum);
 
		System.out.println(Final);
 
	}
	public static double MaxMethod(double L, double M){
		double Temp = L;
		double TempTwo = M;
		double Large;
		if (Temp >= TempTwo);
			Large = Temp;
		if (TempTwo >=Temp);
			Large = TempTwo;
 
			return Large;
}}
I want the larger of the two to be assigned to Large but then how do i pass that back to the top so i can print it[COLOR="Silver"]
 
--- Update ---
 
[/COLOR]import java.util.Scanner;
public class LargerNum {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("Enter two values: ");
		double FirstNum = input.nextDouble();
		double SecondNum = input.nextDouble();
		double Final = MaxMethod(FirstNum, SecondNum);
 
 
 
	}
	public static double MaxMethod(double L, double M){
		double Temp = L;
		double TempTwo = M;
		double Large;
		if (Temp >= TempTwo){
			Large = Temp;}
		else;
 
			Large = TempTwo;
			System.out.println(Large);
			return Large;
 
}}

closer but not there yet please help the second number entered is printed needs to be the larger of the two


in output your asked to enter 2 numbers so say: 9 and 7, 7 will be returned whereas 9 should be returned

import java.util.Scanner;
public class LargerNum {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("Enter two values: ");
		double FirstNum = input.nextDouble();
		double SecondNum = input.nextDouble();
		double Final = MaxMethod(FirstNum, SecondNum);
 
 
 
	}
	public static double MaxMethod(double L, double M){
		double Temp = L;
		double TempTwo = M;
		double Large;
		if (Temp >= TempTwo){
			Large = Temp;}
		else
			Large = TempTwo;
			System.out.println(Large);
			return Large;
 
}}

So it works, but its not doing what it needs to.right now the println is in the max method but it should be in the main method. I dont know how to send the larger value determined from the maxmethod back to the main method so that it can be printed. I have in the max method the final number is to be assigned to the Larger variable, but how do i sent the value of the Larger variable back to the main method.

at the end of the else statement I have return Large which is the larger of the two numbers. So the return Large; line should send the value back to the main method right? so how do i use the value of Large in the main method it wont let me use that variable.

hah! thanks Norm for pointing that out, looks like I was closer than I thought! so here is final code please check:

import java.util.Scanner;
public class LargerNum {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("Enter two values: ");
		double FirstNum = input.nextDouble();
		double SecondNum = input.nextDouble();
		double Final = MaxMethod(FirstNum, SecondNum);
		System.out.println( (int)Final + " is the larger of the two numbers.");
 
 
	}
	public static double MaxMethod(double L, double M){
		double Temp = L;
		double TempTwo = M;
		double Large;
		if (Temp >= TempTwo){
			Large = Temp;}
		else
			Large = TempTwo;
 
			return Large;
 
}
	}

import java.util.Scanner;
public class LargerNum {
	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("Enter two values: ");
		double firstNum = input.nextDouble();
		double secondNum = input.nextDouble();
		double finalNum = maxMethod(firstNum, secondNum);
		System.out.println( (int)finalNum + " is the larger of the two numbers.");
 
 
	}
	public static double maxMethod(double varOne, double varTwo){
 
		double large;
		if (varOne >= varTwo){
			large = varOne;}
		else
			large = varTwo;
			return large;
 
}
	}

ok changed those things does this look more conventional? I need to learn to make my code look better so any suggestions are welcomed

btw, Its not an error but a little bubble says that on the scanner input line that there is a resource leak because input is never closed. not sure what that means. how would i close that input?

ok so i think i should use input.close(); but i cant figure out where to put it. I tried the line after scanner input as well as the line after the println neither worked any suggestions?
